Error update 8 to 9. An exception has been thrown during the rendering of a template

[gigiscol]

Hello. 

I have updated Prestashop from 8 to 9, everything is working fine, the site looks good, but when you access the administrator (backend) it shows an error.

An exception has been thrown during the rendering of a template ("PrestaShop\PrestaShop\Core\Context\CurrencyContext::__construct(): Argument #9 ($precision) must be of type int, string given, called in /public_html/src/Core/Context/CurrencyContextBuilder.php on line 62").

TypeError 

PrestaShop\PrestaShop\Core\Context\CurrencyContext::__construct(): Argument #9 ($precision) must be of type int, string given, called in /public_html/src/Core/Context/CurrencyContextBuilder.php on line 62  

Anyone who can guide me to find the solution? 

Thank you

PHP: 8.1 to 8.4
PS: 9.0.1

Same for me, except that nothing is working anymore (neither FO nor BO) and I don't have CL access to my hosting environment (OVH), so my shop is down and I don't know what to do to revert to a backup.

I'd be grateful for any help!

PS 1.8.2 => 9.0.0

PHP 8.1

I got the same error. The weirdest part about this error is that it didn't show up in a local and an ubuntu vps installation but it does break on my managed hosting environment. There is a discussion here https://github.com/PrestaShop/PrestaShop/issues/38894 but the hosting environment is never mentioned.

edit:
The environment was mentioned here after all https://github.com/PrestaShop/PrestaShop/pull/38905

tl;dr make the following changes

https://github.com/PrestaShop/PrestaShop/pull/38905/files

and the backoffice will probably be fixed.

Hi,
I performed the update to PS9 in a test environment and encountered the same error.
Have you resolved this in any way?

Hi.

./src/Core/Context/CurrencyContextBuilder.php 

Find public function build(), 

change $legacyCurrency->precision to (int)$legacyCurrency->precision

The same is true for me, except my shop is down and I'm not sure how to go back to a backup because neither FO nor BO are functioning anymore, and I don't have CL access to my hosting environment (OVH).
